Machine learning unravels quantum atomic vibrations in materials
Credit: Rosa Romano, EAS Communications/Caltech Caltech scientists have developed an artificial intelligence (AI)–based method that dramatically speeds up calculations of the quantum interactions that take place in materials. In new…
Seeing a trio of entangled photons in one go
Achieving the entanglement measurement of the W state. Credit: KyotoU / Takeuchi lab The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to…
New quantum sensors can withstand extreme pressure
A schematic image shows a 2D sensor squeezed between two diamond anvils. Credit: Chong Zu The world of quantum physics is already mysterious, but what happens when that strange realm…
Microscopes can now watch materials go quantum with liquid helium
Robert Hovden, an associate professor of materials science and engineering, describes how an upgraded cryo-electron microscope works at the Michigan Center for Materials Characterization. Credit: Eric Shaw, Office of the…
Proposed approach could bridge gap between general relativity and quantum mechanics
A circulating fluxon–antifluxon pair in coupled annular Josephson junctions behaves as a detector. The pair decays due to Unruh-induced fluctuations, and the resulting event is observed as a voltage jump.…
In quantum sensing, what beats beating noise? Meeting noise halfway
Credit: Pixabay/CC0 Public Domain Noise is annoying, whether you’re trying to sleep or exploit the laws of quantum physics. Although noise from environmental disturbances will always be with us, a…
Scientist returns to microbial roots and discovers potential quantum computing advancement
Nikhil Malvankar. Credit: Jon Atherton During his Ph.D. at UMass, Nikhil Malvankar was laser-focused on quantum mechanics and the movement of electrons in superconductors. Now a professor at Yale, the…
